One hundred people were surveyed about their favorite kind of yogurt. How many more people prefer chocolate than vanilla?

(vanilla - 25%)

(swirl-35%)

(chocolate - 40%)

a. 10

b. 15

c. 25

d. 40

b) 15

Step-by-step explanation:

Given that,

Total people = 100

% of people prefer vanilla = 25%

Number of people prefer vanilla out of 100 = 25% of 100

=> 25/100 * 100 = 25

% of people prefer swirl = 35%

Number of people prefer swirl out of 100 = 35% of 100

=> 35/100 * 100 = 35

% of people prefer chocolate = 40%

Number of people prefer chocolate out of 100 = 40% of 100

=> 40/100 * 100 = 40

The number of more people preferring chocolate over vanilla = 40 - 25

=> 15 so option b is correct

The answer is B (15)
